Interrupting Edge
An interrupting edge is a type of activity edge drawn as a lighting bolt. It connects a node inside a region to a node outside the region in the same activity. When a token leaves a region via an interrupting edge all other tokens in the region are consumed and all behaviors in the region are halted.
Explanation
When an interrupting edge receives a token all behavior in the region is stopped and all tokens are consumed. This effectively brings the behavior contained in the region to a halt. The interrupting edge is a lightning bolt shaped line and has a similar appearance to an exception edge. The two elements however have different semantics.
